LANTERN.

SPECIFICATION formingpart of Letters Patent No. 232,810, dated October 5, 1880.

Application filed February 4, 1880.

To all whom it may concern.-

Be it known that I, EDWARD P. FOLLETT, a citizen of the United States, residing at Rochester, Monroe county, New York, have invented certain new and useful Improvements in Lanterns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- 7 Figure 1 is a central vertical section of a lantern provided with my improvements. Fig. 2 is a cross-section in line or m, Fig. 1, looking downward. Fig. 3 is a plan of the lower coneplate. Fig. 4 is a section of the same. In Figs. 2, 3, and 4. the views are enlarged.

My improvement relates to sidetube lanterns; and it consists in the construction and arrangement of parts hereinafter more fully described and claimed.

In the drawings, A represents the oil-pot. B B are the side tubes. 0 is the globe or chimney. The side tubes,B 13, extend but part way up and are open at the top. The lower end of the tubes open into a closed chamber, D, which communicates with the burner.

To the top of the side tubes is attached a frame, F, made from a strap of metal and bent into bow form, having two vertical sides, a a, and a curved top, I). This frame serves the double purpose of ways or guides to the sliding top of the lantern and as a stiffener and brace to the top of the side tubes, which are otherwise unsupported, and also as aspring to hold down upon the globe.

G is the sliding dome of the lantern, which is similar to that shown in my patent of April 15, 1879, No. 214,379.

H H are two spring-arms, riveted at c c to the lower plate of the dome, thence extending upward through slots cl d in the top of the dome and slots ffin the frame E. To the tops of the arms are attached the ends of the spring-handle I. The arms have notches g g, which engage with the edges of the slots f f when the dome is forced down to its'lowest position; When the handle is compressed the spring-arms are forced toward each other, the notches are disengaged from the frame, and the dome can then rise.

My improvement as applied to this part of the lantern is as follows: K is an open-ended ring or hoop below the dome, and connected therewith by stays it h, which leave a passage, 2', for the escape of the draft. The hoop rises and falls with the dome, and its lower end fits over and holds the top of the globe. k is a circular projecting ring or flange outside of the hoop, and Z l are two eyes or sockets projecting from the flange,which rest and slide upon the ways a a, as shown in Figs. 1 and 2. These eyes have wings m m, of segmental form, standing vertically and extending some dis tance each way around the ring or flange. an are dividing-plates, which stand upright and extend radially outward from the hoop K to the eyes or sockets l I. These parts all form attachments to the dome G, and rise and fall with it. The eyes or socketsl Z slide freely on -the ways a a and keep the parts in place.

When the hoop is forced down these eyes guide the hoop so that it strikes over the globe, and also bring the dividing-plates n n centrally over the open tops of the side tubes, while the flange 7t projects outward only on a 'line with the inner side of the side tubes.

By the means above described the handle, the spring-arms, the dome, and the hoop, with its connections, form one attachment, which slides up and down, the attachments to the hoop guiding and deflecting the currents of air into the open tops of the side tubes in whichever direction the lantern moves. If, by a sudden motion, the lantern is moved upward, the currents striking the top of flange 70 will be turned downward, arrested by the wings m m, and deflected into the tubes; if it is moved downward the currents strikin g on the under side of flange 70 will also be turned into the side tubes; and if the lantern be moved horizontallyin either direction the vertical dividing-plates n a will also arrest the currents and turn them downward.

L is the supporting-plate for the base of the globe, the same being provided with a central cone, 0, and having in its outer rim a series of perforations, p p, by which air is admitted to the interior of the globe.

M is an interior cone-plate, which forms a cover, resting removably on top of the airchamber D, and supporting on its top the supporting-plate L, as shown in Fig. 1.

The plate M has a series of perforations, W",

in its outer portion, which admit air from the air-chamber D up into the cone 0 of the supporting-plate, and it has in its center a flat or shallow cone, 8, which rests beneath the cone 0, and also has a hole, u, for the passage of the upper end of the wick-tube e, which rests within, but does not reach quite to, the top of the cone 8.

The bottom of the cone 8 is entirely closed by a plate, w, (except the hole for the wicktube,) and through the sides of the cone and close down to the base are a series of air-holes, y g which allow the air to enter from the space between the two plates.

By the use of the arrangement here described the shallow cone 8 becomes very highly heated and converts the oil into gas. The air which enters this cone through the holes 3 y also becomes highly heated and flows out through the slot into the cone above, which also, receiving air from the perforations r 1', mingles with the gas and produces an intense combustion. The flame which escapes above the upper cone is very white and brilliant. The lower cone, by its shallow form and its closed bottom, serves as a rapid heater to the am Having thus described my invention, I do not claim, simply and broadly, a frame at the side of and extending over the lantern upon which the dome slides; but

I claim-- 1. In a lantern, the combination of the side tubes, B B, extending up on a line with the top of the globe and having open ends, and the frame E, attached to the ends of the side tubes and extending over the top of the lantern, the frame forming the ways or guides for the sliding of the dome, and the ends of the side tubes forming the stops to limit the downward movement of the dome in fitting over the globe, as herein shown and described.

2. In a lantern, the combination of the handle I, the spring-arms H H, the dome G, and the ring or hoop K, the ring or hoop forming an attachment to the dome and being provided with the flange 7c, the dividing-plates n a, wings m m, and eyes or sockets l l, sliding on the frame E, as shown and described, and for the purpose specified.

3. In a lantern, the combination, with the su1')porting-plate L, provided with the cone 0, of the interior plate, M, provided with the cone 8, said cone s being shallow, having a closed bottom through which the wick-tube passes, and having holes y y in its sides above the closed bottom, as shown and described, and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
